Map Shows Where New Lithium Mines Could Be Built In Northeast
Summary
Scientists have found large amounts of lithium in the Appalachian Mountains that could supply the U.S. for hundreds of years. Lithium is important for batteries in electric vehicles and clean energy, but mining it will face challenges like strict rules, environmental concerns, and costs.Key Facts
- The U.S. Geological Survey (USGS) estimates lithium in the Appalachians could replace U.S. imports for 328 years at current use levels.
- The Northern Appalachians, mainly western Maine, hold about 900,000 metric tons of lithium in hard rock called pegmatite.
- The Southern Appalachians, from Maryland to Alabama, may contain up to 1.4 million metric tons, mostly in the Carolinas.
- Lithium in rock must be mined using traditional mining methods, unlike extraction from salty water used elsewhere.
- No new lithium mines have been officially planned or announced yet in the Appalachian region.
- Mining would need to overcome strict environmental rules, public opposition, and long approval processes in states like Maine.
- Potential benefits include job creation, tax revenue, infrastructure investment, and support for clean energy industries.
- Interior Secretary Doug Burgum highlighted the findings as a key step toward U.S. mineral independence under President Donald Trump’s administration.
